Copper mines had been wrought in these mountains some centuries ago; but they had been abandoned probably on account of the various revolutions to which this part of India has been subjected. The most common ore which occurs in these mountains is malachite, and it seems to occupy very extensive veins; but the species which I propose to describe

R. Dunne, in Gold Ore Processing (Second Edition), 2016 7.5 Flotation of Copper–Gold Ores. For the bulk flotation of copper minerals and gold from supergene copper ores, it is normal practice to add a xanthate as the primary collector and dithiophosphate as a secondary collector (Bulatovic, 1997).This combination gives satisfactory results in respect of copper concentrate grade and copper

Small ores can be found scattered around on the surface of the ground. These are samples of what ore veins are located within 35 blocks underneath the soil, so they''re somewhat important. In the majority of cases, it is a sample of a vein in the top layer of stone. However, in areas where the top layer is thin enough, the vein may be located in the upper section of the middle stone layer.

Malachite is a copper carbonate hydroxide mineral, with the formula Cu 2 CO 3 (OH) 2.This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation.

Some masses of copper occur that are too large to handle and must be cut by cold chisels, a method that costs more for labor than the value of the metal.

Copper, zinc, gold, and silver have all been sporadically mined from the ore bodies in the period from 1935 to 1966. The ore body occurs as sheets, veins, and lenses located at the contact between metabasalts, banded iron formation and greywackes, and also at fold hinges and along faults and fissures.

Abstract. We will never know who first smelted copper. Nevertheless, archaeometallurgy has made considerable progress in identifying where, when and how our first industrial metal was made into tools. Stone tools had served us well; however, copper proved to be more versatile especially when combined with tin to make bronze.

The ore as mined was not pure as it was mostly encased in rock, combined with earth, and also contained traces of iron ore and other minerals. Firstly it had to be pounded into small fragments on stone tables with rock hammers, then ground to a fine powder of 1-mm grain size in a stone mill (very hard work!).
